现阶段,利用无机水合盐制备相变储能材料已成为一大研究热点,但是单组份无机水合盐相变储能材料的相变温度高,较难适用于温室大棚、室内节能材料等低温应用领域.为了解决这一问题,将CaCl2·6H2O、MgCl2·6H2O以及H2O混合配制出了CaCl2-MgCl2-H2O混盐体系,并采用.T-history方法和差示扫描量热法研究了混盐的体系组成、成核剂添加量等因素对材料相变性能的影响.制备的CaCl2-MgCl2-H2O混盐相变材料可以在25℃以下完全熔解,并且通过改变混盐体系的组成可使材料凝固温度在10℃～20℃范围内可调.此外,本研究在一定程度上解决了无机水合盐相变储能材料在相变过程中的过冷和相分离现象.
